Answer:

The answer is option d which is [tex]7200ft^2[/tex].

Step-by-step explanation:

As Jo counts 20 steps long with 1 step=3 feet so;

length = [tex]20*3=60[/tex] feet

also 40 steps wide with 1 step = 3 feet so;

width = [tex]40*3=120[/tex] feet

thus the area will be

[tex]Area = length * width =[/tex] [tex]60*120=7200ft^2[/tex]

[tex]Area =7200ft^2[/tex]

thus the backyard is 7200 square feet.
